Given numbers are 684, 705, 698, 681
The list of prime factors of all numbers are
Prime factors of 684 are 2 x 2 x 3 x 3 x 19
Prime factors of 705 are 3 x 5 x 47
Prime factors of 698 are 2 x 349
Prime factors of 681 are 3 x 227
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 684, 705, 698, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 705) = 160740
GCD(684, 705) = ( 684 x 705 ) / 160740
= 684 / 705
= 684
Step2:
LCM(3, 698) = 2094
GCD(3, 698) = ( 3 x 698 ) / 2094
= 3 / 698
= 3
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 684, 705, 698, 681 is 1
